Shrink the search box if the width is too small.

[Jun Mukai, 2014/08/28 21:55:36]

Done but I personally prefers to have the original declaration, means
testing::Test

+      model->AddItem(new app_list::test::AppListTestModel::AppListTestItem(
+          base::StringPrintf("id-%" PRIuS, i), model));
+    }
+
+    view_.reset(new AthenaStartPageView(&view_delegate_));

[oshima, 2014/08/28 20:44:52]

The actual code is complicated enough that this should use

GetIconBounds(), rather than icon_bounds().

new line between methods, and cost.

[Jun Mukai, 2014/08/28 21:55:36]

Done.

optional: you can just put it in anonymous namespace.

[oshima, 2014/08/28 20:44:52]

Can you test the re-layout scenario (Wide->narrow->wide)?

Calling this Rotate is a bit confusing. Maybe you can just change it to takes
width and set it from the test?
